External Email - Use Caution
Hi, Douglas
Thanks for your kind reply.
1 I run the same subject on a server with openmp 8 flags cost 7 hours, without openmp 8 flag would be 7h10minutes.
3 Could you be more specific about run them by hand? is this mean I run different tasks like skull strip or parcellation separately within recon rather than recon-all?
Best, Wei

External Email - Use CautionHi, Freesufer experts
My name is wei shao, I have a few questions regarding the parallel computing of recon-all
1 According to documents, freesurfer is OpenMP code , I use -openmp 8 flag like: recon-all -alli -i input.file -s output.file -openmp 8 to tun the recon command on a server, but it doesn't work for me (the running time is very similar for the same subject). Cloud you tell me what is wrong?
Please specify the difference in times.
2 Can Freesufer take advantage of several GPUs?
No
3 Is it possible to open few threads to run recon-all on different sections parallelly?
Only if you run them by hand
Best, Wei
